Their sum is - 1/3 and their difference is 18

Answer:x=53/6 and y=-55/6

Step-by-step explanation:

Let the first number x

Second number b y

Sum of the numbers x+y=-1/3

x-y=18

Solve simultaneously

Using elimination method

We get

2y=-55/3

y=-55/6

Substitute for y in equation 1

x+55/6=18

x=18-55/6

x=53/6
